如何杀死goroutines? [英] How to kill goroutines?

问题描述

我想知道如何杀死/停止goroutines.所有示例均基于频道和选择，这似乎仅在goroutine包含一些可以在频道上收听的重复任务时才有效.有没有办法在下面的goroutine返回之前停止它?

I would like to know how to kill/stop goroutines. All examples are based on channels and select, which seems to only work if the goroutine contains some repeating task between which it can listen on a channel. Is there a way to stop the below goroutine before it returns?

package main

import (
        "time"
)

func main() {
    stop := make(chan string, 1)

    go func() {
        time.Sleep(10 * time.Second)
        stop <- "stop"
        return
    }()
    <- stop
}

推荐答案

是否可以在返回以下goroutine之前停止它?

Is there a way to stop the below goroutine before it returns?

没有(除了调用os.Exit终止整个程序外).

No there is not (except calling os.Exit to abort the whole program).

Goroutines是独立的，无法从外部控制.

Goroutines are self-contained and not controllable from the outside.
